Argon laser treatment is the application of an intense beam of light into the back of the eye, to stabilise or cure a number of eye conditions such as diabetic eye disease, retinal vein occlusions and retinal holes or tears.
This laser was invented in 1964 and was designed to emit a blue/green colored light which is absorbed by hemoglobin in the blood cells. The heat allows the laser to close off ruptured blood cells. An argon laser is a device that uses argon gas and produces a beam of light with a wavelength that is absorbed only by specific pigments such as hemoglobin and melanin, and passes harmlessly through other materials such as fluids. The Argon laser is a unique laser system, as it uses a noble gas as the active medium.
Argon laser has very less divergence (about 1 milli radian) like He-Ne laser. Drawbacks or disadvantages of Argon Laser The Argon laser is a laser system that uses noble gas as the active medium. Argon gas lasers are used in many applications such as forensic medicine, entertainment, general surgery, ophthalmic surgery, holography and as an optical “pumping” source. Argon laser is a common laser used for treating DR. The main spectral peaks of the argon laser are 488 nm (blue) and 514 nm (green) i.e. relatively shorter wavelengths. Modern argon lasers remove blue wavelength light, allowing photocoagulation to be achieved at 514 nm which reduces light scatter as well as preventing absorption of the blue 488-nm wavelength by xanthophyll in the macula.

Een argonlaser of argonionlaser is een gaslaser, meer bepaald een ionlaser, waarbij het actief medium uit argon bestaat. Het argon wordt geïoniseerd en gepompt door een continue elektrische ontlading. Het argon bevindt zich in een gesloten buis, dikwijls met brewstervensters aan de uiteinden voor polarisatie van het licht.
